MACHINE FOR MANUFACTURING CLIPS FOR WAGON-S.

lSPECIFICATION forming' part of Leiters Patent No. 657, 583, dat/edSeptember 11, 1900.

Application filed June 18,1900. Serial No. 20,690. (No model.)

To LZZ whom it may concern.:

Be it known that I, JAMES H. BAKER, a citizen of the UnitedStates,residin g at Allegheny, in the county of Allegheny and State ofPennsylvania, have invented or discovered certain new and usefulImprovements in the Manufacture of Clipsvfor Wagons, duc. ofWhichimprovements the following is a specification.

The invention described herein relates to certain improvements in themanufacture of clips for wagons, dac., and has for its object theproduction of a clip by flattening an intermediate portion of a rod andthen spreading the flattened portion successively in opposite directionsby pressure applied by oppositely-moving surfaces.

The invention is hereinafter more fully described and claimed.

In the accompanying drawings, forming a part of this specification,Figure l is a side elevation of the mechanism employed in the practiceof my invention. Fig. 2 is a top plan view of the same. Fig. 3 is atransverse section, the plane'of section being indicated by the line IIIIII, Fig. 2. Fig. 4 is a top plan view of the anvil or lower die, andFig. 5 illustrates diagrammatically the successive steps in theformation of the clip.

In the practice of my invention the anvilblock or lower die 1 is formedon or secured to a reciprocated bed 2, which'is mounted between suitableguides on the foundation or bed plate 3. The back-and-forth movement ofthe bed 2 can be effected by any suitable means, as the crank-arm 4 onthe power-shaft 5, connected to the bed by a pitm'an 6. A V- shapedgroove 7 is formed in the face of the anvil to form acorrespondingly-shaped rib on the back of the flattened portion of theclip. The end portions 7 of the groove are made sufficiently deep toreceive the ends of the rod operated on, thereby preventing any shapingor distortion of such ends. A hammer or attening-die 8 is arranged insuitable guides in the post or standard 9 and is reciprocated by anysuitable means, such as the crank-arm l0 on the shaft 11, connected bythe pitman l2 to the hammer.

In making clips the heated portion of a rod is placed over the groove 7in the anvil, its end resting against a stop, which in this case isformed by the post 9. As the hammer moves down a section ofthe rod iscut oii" by the blades 13 and 14, one of which is secured to the hammerand the other to the bed-plate 3. By one or more blows of the hammer,preferably one, the middle portion of the cutoif section is flattened,as shown at ct in Fig. 5, and the end portions of the section arepressed down into the portions a of the groove 7 without anymaterialdistortion. The bed 2 is then moved to the right, and duringsuch movement the flattened blank is under the operation of a shoulderor projection 15 on the roll 16, which is caused to rotate by a train ofgearing from the power-shaft i5, so that the projection will move in thesame direction as and with a speed equal to that of the anvil 1 at thisl time. The several parts are so adj usted with relation to each otherthat the front corner w of the projection will strike the flattenedblank about in line with the groove in the anvil if a center clip isdesired, a center clip having the flattened portions extending equallyon opposite sides of a line passing through the axes of the ends of thesection. As the anvil and the projection continue their movement to theright the portion of the blank lying to the left of the groove in theanvil will'be liattened and spread out, as shown ai b in Fig. 5. Themovement of the bed is then reversed, and the partially-formed clip iscarried under the roll 17, which is rotated in a direction the reverseof the roll 16. While the anvil is being moved under this roller, thefront corner of the projection 17a thereon will strike the blank alittle to the left of the groove in the anvil, and by the continuedmovements of the anvil and roll the remaining portion of the blank willbe flattened and spread out, as shown at c in Fig. 5, completing theclip.

While it is preferred to employ a roll having a projection to iatten outthe last portion of the blank, it will be understood by those skilled inthe art that a roll of a radius equal to that of the projection 17a maybe employed. In some cases such a roll would be preferable,

as it would by its.v smoothin g action on the flattened by theprojection prevent'tliejforsl mation of irregularities on the surface ofthe clip. I .s

The upward movement of thelarms is eectedfby the strikingof-iingersl on the! armsaga'inst shoulders 2O as the bed' moves to theleft. yThese shoulders are preferably formed on spltings.-2,l,secnred tothe bed; plate 3.

In order tomake smooth forgings, all loose" scale should be removed frombetween the- .Y blank and anvil yafter each shaping operation.

` mer and the projection on the roll 16.

To this end provision is made for slightly lift-,-

ing the blankafter the operation'of the ham, j Aoon` venient means foreffecting thislifting of the blank consists'in arranging standards 22 onthe bed-plate tothe right of the position of'4 to the left after theoperation of the roll 16.'

A nozzle 23, connected to a source of air un# der pressure, is sosupported that the blast therefrom will blow out the scale when theblank is raised. j

It will be readily understood that by placf ing the rod on the anvil,with its axis in a y plane more or less to one sidev of a plane passingthrough the groove 7, the major part of the blank will be at one side ofsaid; groove and that the finished clip will have more or less of itsflattened portion at one side of a line passing through the axes of itsends orl stems, and, further, by properly timing the action of one ofthe rolls, as 16,0nly said roller need be employed in finishing aclip-as, for example, if said roll be so adjusted that its operativesurface shall comeinto reducing relation to the anvil slightly beforethe front edge of the blank reaches a vertical plane 'passing throughthe axis'of the roll the latter will have a flattening and spreadingaction over the entire surface of the. blank from edge.
